In-describing my invention la'id'of the views above referred to, I desire to-polnt out' that the same are-intended as merely illustrati've ofaxi example whereby .my invention maybe applied in practice, and'ldo notintend to-li 't my invention to 'theprecise construction 'shown'. The following description is vtherefore to be broadly construedas constructions and arinc'luding 'substitute rangement of parts, which are theobvious The signal for the 'rear-'end of an automobile, isin the' form of 'a rectangular casing having a rear wally 1, side walls 2 'and 3, a

bottom-wall 4, atop wa1l5, and detachable? movement to the shafts andp'23` lation of the trafficI 4v of the casing. Associated withthe incan- -descent lamp 10 are reflectors 11 and a vertical partition 12, said partition coperating with the reflectors '11 'in concentrating fr ays of light at the bulls eye 9. The parti- .t1on 12 also coperatiesv withthe bottom wall f4 of the casing in supporting the reflectors hereinafter rel11V and said partition has the upper and lower endsthereof suitably connected to the f` top and bottom' walls 5 and 4 of the casing,.

-as best shown in Fig. 5.' The side edges of the'partition 12 are slitted andbent to provide .reflectors 13 .and these reflectors are adapted tocast rays of light in the direction of transparent'plates14, 1'5 and 16 mounted- 1n a plate holder 17 supported by a strap 1,8.

at an openingr19 in the front Wall 6 of the casing.

The plates wise treated to render portions thereof opaque, the remaining'portions' being transparent and arrow shaped as shown in Fig. .1', wlth the arrows' pointing in opposite di'- rection. The plate 16 is painted or .otherwise treated to render portions thereof opaque with the remaining portions'transparent and representing the characters of the word Stop. -The plates'14,-15 and 14 and 15ers painted or ,other- ,I

tov .l

16 constitute visible signs capableof being illuminated and displayed at night.

The inner sides ofthe walls' 2 1an-d 3 and the bottom wall 4 are provided' with bearings 20 4and 21, said bearings lvertically alining contiguous to the'front lWallx of the casing. Journaled in these bearings are crank shafts 22 and. 23, the former 'being'of a greater height than the latter vfor a purpose. that will be hereinafter appear. The shafts 22 and -23 have crank portions 24ndjacentthe lower ends thereof and engaging j I' I these crank portionsare the ends of armatures 25 fulcrmed, as at 26 linframes 2,7

upon the bottom wall 4' andrearwardly of:

the partition 12. The`r'frames27 support electromagnets 28 .and when 'saidelectroxmagnets are energized the rear ends of the 'armatures 2.5l are'. attracted vand impart f arma-tures extend through openingsprovided therefor in the frames 27 and the partition 12.

pivotal means. The members 32 and 33 ex-. tend through slots v34 in the side wallsl2 and l3, said members having lateralI extensions' 35 normally closing the slots. The outer ends of the members 32 and 33 are provided with right angularly disposed arms 36 havingv the outline' of .an arrow or spear.'

These arms arenormally held in parallelism with the side walls 2 and 3 of the casing,

said arms projecting rearwardly, as best shown in Fig. 2. Theinner ends of the members 32 and 33 are provided with lateral extensions 37 and 38, respectively, said lateral extension engaging shutters 39 and 40 suspended from transverse rods 41, carried bythe sides of the strap 18. The shutters 39 and 40 are at the inner sides of the transparent plate 15 and 14 respectively, and

said shutters have the inner sides thereof provided with curved arms 42 normally engaged by the lateral extensions 37 and 38 of the horizontally disposedI arm members 32 and 33.

Associated with` the transparent plate 16 is an angularly disposed shutter 43 pivoted upon a rod 44 connecting the reiiector 13 of the partition 12. The shutter 43 is supported b' a crank 45 of a rock shaft 46,

ledi

journa n the sides of the strap-18. The

l rock shaft 46 has another crankv 47 engaged by the forward end of an armaturey 48, said armature extending through an opening 49 in the vertically disposed partition 12. The

armature 48 is fulcrumed as at 50 upon a frame 51', vcarried by a bracket 52, secui'ed to the rear lwall' 1 of the casing. The frame 51 has an electromagnet 53 and 'when this magnet is energized, the armature 48 isati tracted and through the medium of the rock shaft 46V and its crank, the shutter 43 is elevated, thereby exposing' the transparent plate 16 to rays of light from the incandescent lamp 1 0. Otherwise the transparent plate 16 is cutuoif from the lower part of the casing and it is impossible for the rays of light to penetrate the shutter 43.

AThe rear Wall 1 of the casing has the' Abuter side thereofv provided with a socket in. .aber 54 as an example. of a fastening means for securing the signal casing to the rear end of an automobile or other vehicle. The bottom wall 4 of the signal casing has binding posts-55 and by reference to'Fig. 3 of the drawings, it will be observed that a suitable source of electrical energy, as battery cells -56 and push buttons 57, 518 and 59 are electrically connected With the 'three .electromagnets within thesignal, casing. The push buttons 57, 58'and 59 controlthethree circuits of the signal and as an instanceof Va circuit controlling -the operation of .the

stop7 shutter 43, the push button 58 is connected to the electromagnet 53bya'wire 60, the electromagnet connectedby a wire 61 to the battery 'cells 56, and the battery cells 56 by wires 62 and 63 to the push .button 58.

Assuming that one 'of the other push buttons is pressed to closel ay circuit and energize one of the' electromagnets 28, the armature 25 of the. electromagnetis attracted vand' one of the vertically disposed crank shafts 22 or 23 'is actuated. 'Furtherassuming that the shaft 22 is actuated,-the member 32 at the upper end 'ofthe shaft is swung in a lateral plane into thev casing, thereby swinging the arm 36 forwardly. at right angles to the-wall 2 ofthe casing, positioning the arm as shown" indotted lines 'of Fig. 2. Simultaneous with this'operation the extension 37 of the member 32 shifts the arm 42 of the shutter 39, elevating said shutter and exposingthe 'transparent plate 16 to rays of light emitted by the' incandescent lamp 10. It is to'be noted that when the shutter -39 -is closed that the lateral extenlsion 37'engages the inner side"ofthe frame,

as shown in Fig. 2, thereby preventing the shutter fromv accidentally movingor rattling. This is also true in connection with the shutter 40 and since the shutter 43 rests upon the crank 45 and closes by gravity,

there is little danger of this shutter` accidentally opening.

3. In an automobile traic signal, a casing, members pivotally mounted in said casing 4and extending through the side walls thereof, arms carried by said members, signs forming part of said casing, shutters at the innersides of said sign and held normally in parallelism therewith by said members, means carried by said shutters and engaged. by said members whereby said shutters can be opened, and means including shafts adapted to actuate said members whereby said arms and shutters are simultaneously moved.
